During my first sabbatical at Orsay, working with A. Capella, U. Sukhatme, and Tran Thanh Van, we began an exploration of the consequences of the Pomeron having the desired topological structure, as suggested by string theory in general and DTU in particular. These studies were vigorously discussed and confronted with experiments. In particular, these were carried out regularly at annual Moriond meetings. Based on the initial success, a systematic calculus was formulated, which has subsequently dubbed the “Dual Parton Model" (DPM)[1]}. This is partly based on the general approach to the S-matrix bootstrap advocated by Veneziano [2]} and also adopted by Geoff [3]}. The details of this model were discussed in the contribution The Pomeron Story, and will not be repeated here. (See Ref. [1]} and also the contribution of G. Veneziano in this volume.) Here we illustrate the key features by two schematics in Fig. REF .
